Definitions

  • the invention relates to a multilayer laminate, wherein the laminate surfaces Made of polyethylene.
  • Tubes with a so-called barrier layer additionally have a barrier layer arranged inside the laminates the passage of water vapor and gases, e.g. an aluminum foil, on.
  • the Cover layers, which form the laminate surfaces, consist of Polyethylene, as in the manufacture of the tube body of laminates, the be made by extrusion lamination or by cast method, the inside is sealed against the outside.
  • Tubes are used, among other things, for the packaging of cosmetic and pharmaceutical products used.
  • these product lines there is a desire to be the consumer to convey the high quality of the products through the packaging.
  • the invention is based on the object, a suitable for the production of tubes Laminate of the type mentioned to create, which at least Equipped with an aesthetically pleasing surface effect on one side is.
  • At least one side the laminate comprises a spunbond fabric made of polyethylene fibers.
  • spunbonded fabric here, for example, falls under the brand name Tyvek® product known by DuPont.
  • the product is won by the spinning of endless strands of very finely interwoven, undirected 100% high density polyethylene (HDPE) fibers, which are then passed through the Exposure to heat and pressure to be welded into a film.
  • HDPE high density polyethylene
  • the spunbonded according to the invention gives the laminate surface a satin luster and leads to a "soft-touch" surface with a more pleasant Haptics.
  • the spunbonded fabric can be dyed and provides a good printable surface at.
  • the spunbonded nonwoven preferably consists of a high density polyethylene (HDPE).
  • HDPE high density polyethylene
  • the thickness of the spunbonded fabric is preferably 50 to 220 ⁇ m.
  • both sides of the laminate according to the invention can Spunbonding include. However, this might only make sense for cost reasons when both sides of the laminate are visible to the viewer.
  • one of the laminate surfaces can be a polyethylene on both sides coated polypropylene compound film, LMDPE, LLDPE or LDPE film or a film of foamed polyethylene.
  • a polyethylene-coated polypropylene compound film on both sides the laminate has a higher rigidity, so that with a laminate with pure polyethylene layers achievable stiffness even at a lower laminate thickness is reached.
  • the reduced by the reduced thickness material requirement ultimately leads to a less expensive laminate.
  • the polypropylene compound film can e.g. a polypropylene / polyethylene compound film with a Preferably greater than 50% by weight of polypropylene.
  • the on both Side of the polypropylene compound film arranged polyethylene layers preferably have a thickness of 10 to 30 microns.
  • the preferred thickness of the Polypropylene compound film is 20 to 80 microns.
  • a foamed polyethylene film can also save weight and a further improved stiffness of the laminate can be achieved.
  • the foamed film shows a better sliding behavior u. a. versus Steel, which makes tube production safer.
  • a barrier layer against the Passage of water vapor and gases can be arranged.
  • barrier layer may be a metal foil of, for example, aluminum.
  • suitable Materials for barrier layers are, for example, films made of plastics, such as polyvinylidene chloride (PVDC), ethyl vinyl alcohol (EVOH), polyamide (PA) or polyamide blends, in the thickness range between about 3 and 25 microns, or a layer of ceramic materials, such as silicon or aluminum oxide or nitride used as a thin layer in the range of About 10 - 500 nm are deposited in vacuum on the carrier film.
  • PVDC polyvinylidene chloride
  • EVOH ethyl vinyl alcohol
  • PA polyamide
  • barrier layers are metallic layers, e.g. made of aluminium, for example, by sputtering or by deposition from the vacuum deposited on the plastic film in a thickness of about 10 nm to about 2 microns become.
  • an aluminum foil is suitable, the laminate in addition to the barrier properties, which is the passage of liquids, Avoid gases, vapors, steam, aromas or odors, additional to give mechanical stability.
  • VA polyethylene-vinyl acetate
  • Polyethylene layers can also be an intermediate layer of an ethylene copolymer, especially an ethylene-acrylic acid (E.AA) copolymer arranged be.
  • E.AA ethylene-acrylic acid
  • the preferred thickness of the aluminum foil is 5 to 40 microns, the preferred Total thickness of the laminate is 150 to 350 ⁇ m.
  • the laminate according to the invention is preferred for the production of tube bodies used.
  • 1 shows the structure of a first, a total thickness of 245 microns having tube laminate 10, which has the following structure from the tube outside to the tube inside out: 12 HDPE spunbonded, white, 160 ⁇ m 14, 15 coextruded PENA film, white, 17 ⁇ m 16 Aluminum foil, 6.3 ⁇ m 18 E.AA copolymer film, 17 ⁇ m 19 PE film, 15 ⁇ m 20 PE / PP compound film, 15 ⁇ m 21 PE film, 15 ⁇ m
  • the HDPE spunbond 12 and the PP / PE compound film 20 with the two-sided PE layers 19, 21 are, for example, via the coextruded PENA film 14, 15 or via the E.AA copolymer film 18 with the aluminum foil 16 laminated.
  • Fig. 2 shows the structure of a tube laminate 110 corresponding to the tube laminate 10 of Fig. 1, but instead of the PP / PE compound film 20 with the two-sided PE layers 19, 21, a foamed PE film 22 forms the tube inside.
  • the tube laminate 110 with a total thickness of 275 ⁇ m has the following structure from the outside of the tube to the inside of the tube: 12 HDPE spunbonded, white, 160 ⁇ m 14.15 coextruded PENA film, white, 24 ⁇ m 16 Aluminum foil, 6.3 ⁇ m 18 E.AA copolymer film, 24 ⁇ m 22 PE film, foamed, 60 ⁇ m
  • Fig. 3 shows the structure of a tube laminate 210 corresponding to the tube laminate 110 of Fig. 1, but instead of the PP / PE compound film 20 with the two-sided PE layers 19, 21, an LMDPE film 24 forms the tube inside.
  • the tube laminate 210 with a total thickness of 275 ⁇ m has the following structure from the outside of the tube to the inside of the tube: 12 HDPE spunbonded, white, 160 ⁇ m 14.15 coextruded PENA film, white, 20 ⁇ m 16 Aluminum foil, 12 ⁇ m 18 E.AA copolymer film, 20 ⁇ m 24 LMDPE film, 60 ⁇ m
